Will possibly be done around L+10 line_7: days with the flood guiding check test. line_12: The North Orbit Pole pointing will keep the WF/PC radiator facing the Earth in line_13: a "hot orbit" condition. ! ! end of abstract general_form_proposers: lname: DANIELSON fname: G. mi: E. inst: CALTECH country: USA ! lname: WESTPHAL fname: JAMES mi: A. inst: CALTECH country: USA ! lname: GUNN fname: JAMES mi: E. inst: PRINCETON UNIVERSITY country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 0 line_1: This test sequence establishes a WF/PC system baseline and line_2: monitors the camera performance in the UV at the beginning line_3: and at the end of the test. This should drive all line_4: contaminates from the CCDs. ! question: 3 section: 0 line_1: Initial WF/PC High Temperature Decontamination: line_3: 1. Take a series of UV Baseline exposures. line_5: 2. Point the S/C toward North Orbit Pole (i.e. "hot orbit") for 8H.
